Isaiah 6:2

6:2 Seraphs ¹  stood over him; each one had six wings. With two wings they covered their faces, with two they covered their feet, ²  and they used the remaining two to fly.

Isaiah 27:12

27:12 At that time ³  the Lord will shake the tree, ⁴  from the Euphrates River ⁵  to the Stream of Egypt. Then you will be gathered up one by one, O Israelites. ⁶ 

[6:2]  ¹ tn Hebrew שָׂרָף (saraf, “seraph”) literally means “burning one,” perhaps suggesting that these creatures had a fiery appearance (cf. TEV, CEV “flaming creatures”; NCV “heavenly creatures of fire”). Elsewhere in the OT the word “seraph” refers to poisonous snakes (Num 21:6; Deut 8:15; Isa 14:29; 30:6). Perhaps they were called “burning ones” because of their appearance or the effect of their venomous bites, which would cause a victim to burn up with fever. It is possible that the seraphs seen by Isaiah were at least partially serpentine in appearance. Though it might seem strange for a snake-like creature to have wings, two of the texts where “seraphs” are snakes describe them as “flying” (Isa 14:29; 30:6), perhaps referring to their darting movements. See the note at 14:29.

[6:2]  ² sn Some understand “feet” here as a euphemistic reference to the genitals.

[27:12]  ³ tn Heb “and it will be in that day.” The verb that introduces this verse serves as a discourse particle and is untranslated; see note on “in the future” in 2:2.

[27:12]  ⁴ tn Heb “the Lord will beat out.” The verb is used of beating seeds or grain to separate the husk from the kernel (see Judg 6:11; Ruth 2:17; Isa 28:27), and of beating the olives off the olive tree (Deut 24:20). The latter metaphor may be in view here, where a tree metaphor has been employed in the preceding verses. See also 17:6.

[27:12]  ⁵ tn Heb “the river,” a frequent designation in the OT for the Euphrates. For clarity most modern English versions substitute the name “Euphrates” for “the river” here.

[27:12]  ⁶ sn The Israelites will be freed from exile (likened to beating the olives off the tree) and then gathered (likened to collecting the olives).
